National Dam Safety Program. Riss Lake Dam (MO 20128), Missouri - Kansas City Basin, Jackson County, Missouri. Phase I Inspection Report

摘要

Riss Lake Dam was inspected by an interdisciplinary team of engineers. The purpose of the inspection was to make an assessment of the general condition of the dam with respect to safety, based upon available data and visual inspection, in order to determine if the dam poses hazards to human life property. Our inspection and evaluation indicates that the spillway does not meet the criteria set forth in the guidelines for a dam having the above size and hazard potential. The spillway will not pass a 100-year flood (flood having a one percent chance of being exceeded in any year). The spillway will pass 12% of the Probable Maximum Flood without overtopping the dam. The Probable Maximum Flood (PMF) is defined as the flood that may be expected from the most severe combination of critical meteorologic and hydrologic conditions that are reasonably possible in the region.
